I am very sure that Clojure guarantees this. In a pure functional language (like Haskell) this has not to be the case. As there are no side effects it absolutely does not matter at all in what order anything is evaluated. But Clojure is a functional and imperative language, and for running Java we need this guarantee. At a first glance I see no need for implementing that in the core language, and also not as a macro. This can easily be implemented as a function, as Robert demonstrated. I also don’t see how the function hides the “do the rest” part. Maybe returning is not the best name, but how would we benefit of a macro, which is more complicated and also is not first class and can’t be passed around? --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Clojure" group.
